Description

Technical Field

[0001] The utility model belongs to the field of air coolers, and in particular relates to a hook feeding device for cleaning fin tubes. Background Art

[0002] Finned tubes are made of metal tubes and steel strips welded by welding equipment. They are mainly used in air coolers to cooperate with other components to achieve heat exchange.

[0003] Due to the particularity of the working environment of the fin tube, it is usually necessary to clean the surface of the fin tube to increase its service life and maintain good heat dissipation. Before cleaning the existing fin tube, hooks need to be inserted at both ends of the fin tube, and then the upper end of the hook is connected to the transmission chain so that the transmission chain can send the fin tube into the cleaning device for cleaning.

[0004] The existing hook insertion method is to manually insert the lower end of the hook into the holes at both ends of the fin tube, and then connect the upper end of the hook with the hook on the transmission chain. Since the lower end of the hook and the end of the fin tube are connected only by the hook, the hook needs to be held manually before the hook is connected to prevent the hook from falling. The labor cost is large, and the connection between the hook and the fin tube is unstable. When the upper end of the hook is connected to the hook, the lower end of the hook is easy to slip out of the fin tube, posing a safety hazard. Utility Model Content

[0005] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a hook feeding device for fin tube cleaning, which can automatically insert the hooks into both ends of the fin tube, improve the degree of automation, and prevent the hooks from slipping when the fin tube is hung, thereby having high safety.

[0010] Furthermore, the hook placement assembly includes a placement table, a placement groove is provided along the length direction of the placement table, and its cross-section is L-shaped. The upper end of the vertical part of the placement groove passes through the upper end of the placement table, one end of the horizontal part is provided with a accommodating cavity, and one end of the placement groove is provided with a feeding groove, and the pushing assembly is movably arranged in the feeding groove.

[0011] Furthermore, a group of spaced movable grooves are provided on one side of the feed trough, and the pushing assembly includes a second cylinder arranged on one side of the placement table, and a cross plate is provided at its output end, and push blocks are provided at both ends of the cross plate. The push blocks are slidably arranged in the movable groove, and a U-shaped groove is provided at one end of the push block, and the opening direction of the U-shaped groove is consistent with the feeding direction of the hook.

[0012] Furthermore, a guide groove is provided on one side of the feed trough, in which a limit assembly is provided. The limit assembly is located on one side of the vertical portion of the placement groove and is used to limit the moving direction of the hook.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0026] like Figure 1-Figure 6 As shown, this embodiment provides a hook feeding device for fin tube cleaning, comprising a frame 100 and feeding parts 200 respectively arranged on both sides of the frame 100. The frame 100 is used to place the fin tube 2 to be processed, and the feeding part 200 is used to move along the length direction of the frame 100 and insert the hook 1 into both ends of the fin tube 2.

[0027] Specifically, Figure 1-Figure 3 As shown, the middle part of the frame 100 is recessed downward to form a discharge trough 110 for temporarily storing the fin tubes 2 to be processed. The top walls on the left and right sides of the discharge trough 110 are provided with support plates 120 extending outward. The loading part 200 is movably arranged along the length direction of the support plate 120. A first cylinder 121 is arranged at one end of the support plate 120 to provide power for the movement of the loading part 200.

[0028] The loading part 200 includes a hook placement component 210 and a push component 220 arranged at one end of the hook placement component 210. The hook placement component 210 is used to temporarily store the hook 1, and the push component 220 is used to push the hook 1 one by one along one end of the hook placement component 210, and insert the hook 1 into one end of the fin tube 2. In order to keep the hook 1 stable after being inserted into the end of the fin tube 2, a truncated cone 11 is provided at the insertion end of the hook 1, and the small end of the truncated cone 11 faces one end of the fin tube 2. A baffle is provided at the other end of the truncated cone 11. The baffle is used to block the movement of the truncated cone 11 after the hook 1 is inserted into the end of the fin tube 2, so as to force the truncated cone 11 to be inserted into the end of the fin tube 2. In order to increase the friction between the truncated cone 11 and the fin tube 2, the truncated cone 11 is made of rubber material to prevent the hook 1 from slipping during the hoisting process, and the safety is good.

[0029] Specifically, Figure 1-Figure 2 As shown, the hook placement assembly 210 includes a placement platform 211, the length direction of the placement platform 211 is consistent with the length direction of the support plate 120, and a placement groove 212 is provided along the length direction of the placement platform 211. The cross section of the placement groove 212 is L-shaped, the vertical portion of the placement groove 212 passes through the top of the placement platform 211, the front end of the horizontal portion is closed, and a receiving cavity 217 for receiving the truncated cone 11 is provided at the front end of the horizontal portion. A feed groove 213 is provided at one end of the placement groove 212 facing the first cylinder 121, that is, the length direction of the feed groove 213 is perpendicular to the length direction of the placement groove 212, and the feed groove 213 passes through one side of the placement platform 211 facing the discharge groove 110. The push assembly 220 is movably arranged in the feed groove 213, and is used to push the hook 1 along the feed groove 213 to insert the end of the fin tube 2.

[0030] Preferably, in order to enable the hook 1 to automatically move from the placement groove 212 to the feed groove 213, the bottom surface of the horizontal part of the placement groove 212 can be set as an inclined surface, so that the lower end of the inclined surface is connected to the feed groove 213, and a linear mechanism can be set at one end of the placement table 211, so that the linear mechanism pushes the hook 1 to move along the length direction of the placement groove 212, thereby realizing automatic loading.

[0031] Specifically, Figure 3-Figure 5As shown, a group of movable grooves 214 are provided on the side opposite to one end of the feeding groove 213 and the placement groove 212, and there is a gap between the two movable grooves 214, and the pushing assembly 220 includes a second cylinder 221 arranged on the side of the placement table 211 away from the discharge groove 110, and a cross plate 222 is provided at its output end, and push blocks 223 are respectively provided at both ends of the cross plate 222, one side of the push block 223 is slidably matched with the movable groove 214, and one end of the push block 223 is provided with a U-shaped groove 224, and the opening direction of the U-shaped groove 224 is consistent with the feeding direction of the hook 1. When the hook 1 enters the feed trough 213, the second cylinder 221 is started to push the cross plate 222 to move, so that the push block 223 moves along the moving groove 214, so that the vertical section of the hook 1 enters the U-shaped groove 224, and as the push block 223 moves, the two U-shaped grooves 224 act on the vertical section of the hook 1, so that the hook 1 is evenly stressed when being inserted into the fin tube 2.

[0032] Specifically, a guide groove 215 is provided on one side of the feed trough 213, and the guide groove 215 is located between the two moving grooves 214, and the other end of the guide groove 215 corresponds to the connection between the horizontal part and the vertical part of the placement trough 212. A limit assembly 230 is provided in the guide groove 215, and the limit assembly 230 is located on one side of the vertical part of the placement trough 212, that is, the limit assembly 230 is located above the horizontal part of the placement trough 212. The limit assembly 230 is used to limit the vertical part of the hook 1 after the hook 1 enters the feed trough 213, so as to prevent the hook 1 from tipping toward the direction of the discharge trough 110.

[0033] Specifically, Figure 3-Figure 4 As shown, the limit assembly 230 includes a guide rod 231, a spring 232, a limit seat 233, a limit plate 234, and a torsion spring 235. The two ends of the guide rod 231 are respectively connected to the two ends of the guide groove 215, the spring 232 is passed through the guide rod 231, the limit seat 233 is slidably matched with the guide groove 215, and is passed through the guide rod 231. One end of the spring 232 is connected to one end of the guide groove 215, and the other end is connected to one side of the limit seat 233. The limit plate 234 and the limit seat 233 extend out of one end of the guide groove 215, and a torsion spring 235 is provided between the limit plate 234 and the limit seat 233. It is worth noting that the thrust of the push block 223 is greater than the elastic force of the spring 232. When in use, the push block 223 pushes the vertical part of the hook 1, so that the hook 1 moves toward the end of the fin tube 2. When the small end of the frustum 11 contacts the end of the fin tube 2, the limit seat 233 moves to the end of the guide groove 215 toward the discharge trough 110. At this time, as the push block 223 moves, the limit seat 233 remains stationary, and the limit plate 234 rotates along the connection between the limit plate 234 and the limit seat 233, and makes one side of the limit plate 234 fit with one side of the feed trough 213. When the frustum 11 of the hook 1 is inserted into the end of the fin tube 2, the limit plate 234 automatically resets under the action of the torsion spring 235.

[0034] Specifically, Figure 1-Figure 2 As shown, in order to ensure better stability when the placement platform 211 moves, a guide bar 216 is provided at the bottom of the placement platform 211, and a slide groove 122 is opened along the length direction of the support plate 120 so that the guide bar 216 and the slide groove 122 can slide together.

[0035] Specific operation process:

[0036] The fin tubes 2 to be processed are hoisted into the discharge trough 110 in sequence, and then the hooks 1 are installed into the placement trough 212 in sequence, and the truncated cone 11 is kept in the accommodating cavity 217, so that the hooks 1 in the feed trough 213 correspond to the hooking points at both ends of the fin tube 2, and the second cylinder 221 is started to push the cross plate 222 to move, so that the push block 223 pushes the vertical part of the hook 1 to move toward the end of the fin tube 2. When the lower end of the truncated cone 11 contacts the end of the fin tube 2, the limit seat 233 stops moving, and as the push block 223 moves, the vertical part of the hook 1 moves toward the end of the fin tube 2. With the continuous pushing of block 223, the vertical part of hook 1 pushes the limit plate 234 to rotate, thereby avoiding hook 1, allowing the frustum 11 to completely enter the end of the fin tube 2, so that the two ends of the fin tube 2 are inserted into the hook 1. After the insertion is completed, the first cylinder 121 is started, so that the first cylinder 121 pushes the placement table 211 to move to the two ends of the next fin tube 2, and repeats the above insertion process of the hook 1, and then the upper end of the hook 1 is hung on the hook of the transmission chain, so that the transmission chain transports the fin tube 2 to the cleaning device for cleaning.

[0037] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
